GAS-HEATED SAD-IRON.

riot ta Application filed February 19, 1913.

To all whom it may concern Be it known that I, HARRY A. KonNIG, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Gas- Heated Sad-Irons, of which the following is a specification.

This invention relates generally to sad irons and more particularly to a gas heated sad iron, the object being to provide an exceedingly simple andhighly efficient form of iron which will prevent smoking or sooting of fabrics during the operation. of ironing and which will also prevent the emitting of odors, vapors or gases ordinarily due to imperfect combustion caused by irregular drafts during the ironing operation.

Gas heated sad irons have usually been constructed with air inlet openings adjacent the bottom, and these I have found objectionable for the reason that as the iron is moved back and forth in the operation of ironing there is a tendency to produce cross currents or drafts which interfere with combustion and at times cause jets of flame to shoot out through the openings and at other times these openings become covered by portions of the fabric being ironed and thereby cut-off the supply of air at that point which is calculated to interfere with perfect combustion and consequently pro duce odors. Furthermore the edges of these openings frequently become rusted, which rust is liable to flake off upon the clothes being ironed. Furthermore by having the openings adjacent the bottom there is a possibility of a flare back which might prove dangerous.

The object of my invention therefore is to avoid all these objectionable features and this I accomplish by producing a sad iron body with imperforate sides and construct ing the bottom of said body portion with an air reservoir which is supplied from an opening in the rear of the body, and in connection with the said iron body of the above construction I employ a burner pipe which is projected through the rear end of said iron body and positioned directly above the air reservoir in the bottom, a suitable cover being employed in connection with the hollow body and to which the handle is attached.

Specification of Letters Patent.

Patented Aug. f8, 1914.

Serial No. 749,444.

The invention consists in certain details of construction hereinafter fully described and pointed out in the claim.

In the drawings forming a part of this specification: Figure 1. is a vertical longitudinal sectional view of a sad iron con structed in accordance with my invention. Fig. 2 is a top plan viewof the same, the cover being removed. hi 3 is a transverse vertical section on the line 53 of Fig. 1, and Fig. l is a rear end view.

in carrying out my invention I employ a hollow sad iron body of suitable size and. shape, the sides and bottom thereof imperforate. The sides are cut away slightly at the upper edges as shown at A, and the rear end is also cut away at definite points along its upper edge as shown at A Any suitable form of cover B is attached to the top of the body portion by screws at the front and rear ends and to this cover is attached the usual or approved handle C.

The rear end of the body portion is formed with a central opening D, through which the burner pipe is passed, said burner pipe having a series of jet openings E produced in the bottom thereof upon opposite sides of the longitudinal center of said pipe. This burner pipe E at its rear end is connected. to the usual gas tube and. is provided with air inlet openings after the usual manner of Bunsen burners. This burner tube or pipe E is positioned within the hollow body a suitable distance above the bottom thereof and extends the entire length of said body, the forward end of said burner tube or pipe being externally threaded and screwed into the threaded recess F which is made in. the forward end of this hollow body, this con nection thereby effectively closing said end and also securely connecting the burner tube or pipe to the body of the iron and maintaining it in its proper position within the said sad iron body.

The bottom of the body A, is formed with an air reservoir G, which is open at the rear end and extends substantially the entire length of the body. This air reservoir G is formed by coring out the bottom and cutting a longitudinal slot so as to produce a longitudinal chamber which is essentially rectangular in cross section and which communicates with the body of the iron through the longitudinal slot opening G. The rear end of the body is formed with an opening H, which in size and shape corresponds exactly with the chamber or reservoir Gr, formed in the bottom, and through which air enters. The longitudinal slot or opening G is directly beneath the burner tube or pipe E and consequently when said burner is lighted the heated products generated tending to rise will draw in through the opening H and chamber G the proper amount of air to produce perfect combustion of the commingled air and gas supplied to the burner tube or pipe E.

By means of this ccnstruction or bottom taken in connection with the burner tube or pipe position as herein shown I am able to overcome all of the objections hereinbefore referred to and provide an exceedingly si1nple construction of sad iron which can be quickly and easily heated.

The shape of the air chamber or reservoir in the bottom of the sad iron may be changed or varied slightly without departing from the broad principle of my invention.

WVhat I claim is In a sad iron, the combination with a body the rear end thereof having an air inlet opening and a burner tube opening, the bottom of said body having a longitudinal air chamber therein communicating at its rear end with the air inlet opening, and communicating with the interior of the bottom through the medium of the longitudinal opening, and a burner tube passing'through the rear end of body and positioned above the longitudinal air chamber in the bottom and means for connecting the forward end of said tube to the forward end of the iron and simultaneously closing the end of said tube as set forth.
